Containment measures and restrictions due to Coronavirus Covid-19 are gradually loosening but prudence is never too much, therefore it becomes essential to have tools for prevention, such as the new gadget that Xiaomi has offered for sale on its crowdfunding showcase Youpin, which has already become a best seller following the high demand from online users. Let's talk about the Yuwell YX303 pulse oximeter, a brand we already know for other health-themed gadgets.
Il pulse oximeter, also called a saturator or oxygen saturation meter as well as oximeter, it is a medical instrument used to indirectly measure the heart rate and oxygen saturation detected in a patient's blood. To measure these two parameters, the gadget is placed on the end of a finger which, using sensors, will return the result visible on the small screen it is equipped with. This technique is less invasive than the direct control of the oxygen level in the blood, still obtaining very reliable results.
The Yuwell YX303 pulse oximeter emits light with two different wavelengths, respectively 660nm and 940nm, red and infrared. This light is widely absorbed by the connective tissue, skin, bones and blood of the veins. Infrared light is absorbed by oxygenated hemoglobin, causing more red light to pass through and this is absorbed by deoxygenated hemoglobin, allowing more infrared light to pass through. On the opposite side of the oximeter is a photodetector, which is responsible for controlling the amount of light that has passed through the finger and has not been absorbed. To obtain the result, the pulse oximeter photodetector compares the speed of the red light with the speed of the infrared light, determining the oxygen saturation level.
Yuwell's greeting gadget has a clamp shape and a weight of 54 grams, allowing transportation in any situation, so much so that it can also be kept in your pocket. We find a two-color LED screen and by means of a button, the user is able to view various information as well as perform measurements. Everything is powered by a 30 mAh rechargeable battery, while in terms of energy saving, there is a function that will automatically turn off the product if no measurement is detected after 8 seconds.
A very useful gadget for all those who want to know their physical conditions as well as joining sports with fitness tracker for a better sports clinical picture. The product also arrived in Italy through the Amazon store, but at the moment it is not available due to the high demand. Keep an eye on it because there are many testimonials in which such a gadget saved many people's lives.
